Due to a high number of full-grown woody species that bear plates with the Czech and Latin names, the park started to be called the arboretum, although it does not exactly correspond to the definition of this term. The name “arboretum” comes from the Latin word “arbour” which means a tree. In fact, arboretum is a domesticated, common name for a specialized garden or another land with cultivated woody species of various both domestic and exotic origin, maintained as a park or a collection of woody species serving for experimental cultivation or another research programme of a different focus. The main specialized activity and a scientific branch pursued in the arboretum is the woody species science, dendrology, a specialized branch of botany.
